The Klarzone KZL series was developed to eliminate odors and smoke from commercial kitchen exhaust systems without chemicals .
The UV-C filter of the Klarzone KZL series breaks down odor molecules and organic compounds in the exhaust air of commercial kitchens. Purification is purely physical, using UV-C light and oxidation, entirely without chemicals. This reliably reduces odors and smoke components before the air is discharged.
A UV-C filter removes odors through oxidation. The short-wave UV-C light breaks down organic odor and smoke molecules and neutralises them together with the ozone produced in the process. This process, also known as photolysis and oxidation, reduces odor-forming compounds directly in the airflow.
Because the reaction takes place immediately in the exhaust duct, odors are significantly reduced even before the activated carbon stage. This relieves the downstream filters and improves the overall performance of the system.
UV-C filters and activated carbon filters perform different tasks in odor removal. The UV-C filter breaks down organic molecules through oxidation, while the activated carbon filter binds the remaining residual gases on its surface through adsorption. In combination, the two technologies complement each other and achieve the most reliable odor reduction.
For this reason, UV-C and activated carbon are used together in the ecology unit of the KZT series, complemented by an upstream electrostatic filter stage.
The UV-C filter operates completely chemical-free and compact. Apart from the regular replacement of the UV-C lamps, it requires no ongoing consumables and, in addition to odors, also reduces germs in the airflow. This contributes to hygienic and low-odor exhaust air.
Especially in kitchens with strong smoke and odor development, the UV-C filter improves air quality and supports compliance with regulatory requirements for odor reduction.
The KZL series comprises three models that differ in air capacity and the number of UV-C lamps. The KZL-25 offers an air capacity of 2,500 cubic metres per hour with four UV-C lamps. The KZL-50 delivers 5,000 cubic metres per hour with eight lamps, and the KZL-75 reaches 7,500 cubic metres per hour with twelve lamps. All models operate with a lamp power of 80 watts and a lamp diameter of 15 millimetres.
The UV-C filter is suitable for commercial kitchens with high smoke and odor development, such as restaurants, hotels, industrial kitchens and catering operations. It is mostly used as part of a multi-stage system, where it works together with electrostatic filters and activated carbon filters to fully clean the exhaust air.
Yes, UV-C filtration works purely physically and does not require the use of chemicals. The odor and smoke molecules are broken down by UV-C light and oxidation, without releasing any additional substances into the air.
Ozone is produced in the UV-C process and is used to oxidise the odor molecules. Because the reaction takes place in a closed system within the exhaust duct, the process remains controlled and safe. The system is designed so that the ozone reacts within the system and does not reach the surroundings in an uncontrolled manner.
The UV-C lamps are replaced once their radiation output declines. The replacement interval depends on the operating hours and the load on the system and is determined on a project-specific basis to ensure consistent cleaning performance.
